          Gao Fu, head of the Chinese Center for Disease Control and Prevention, said investigating the origin of the virus is a scientific question that should be answered scientifically.

          The pathogen may gain new properties by mutating and then breaching the body's immune system. Therefore, it is important to enhance international scientific cooperation based on openness, trust and collaboration, Gao said.
